Tectonic elements of the Puerto Rico northern peninsular slope are the creations of Mesozoic-Paleogene southerly directed subduction which formed an island arc-forearc basin-accretionarywedge complex, Oligocene-Pliocene carbonate platform construction during a tectonically stable phase, a northerly collapse of the carbonate platform and subsidence of the Puerto RicoTrench in the Pliocene and the initiation of the present oblique subduction regime in theQuaternary. Collapse of the platform and trench may be due to extension of the Greater AntillesRidge caused by counterclockwise rotation of Puerto Rico-Virgin Islands platelet resulting froma change in plate geometry in the Miocene-Pliocene.
